Multiple supernova explosions about 65 light-years away may have contributed to the ozone depletion and several subsequent extinction events at the Devonian-Carboniferous...
Astronomers have for the first time used X-ray imaging to examine a calcium-rich supernova. Their findings, published in the Astrophysical Journal, show...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found new evidence that a very young neutron star is hiding deep inside...
Astrophysicists and cosmologists from the Sloan Digital Sky Survey (SDSS) have released the largest 3D map of the Universe ever created, filling in the...
A white dwarf star called SDSS J124043.01+671034.68 (SDSS J1240+6710) is traveling at 900,000 km/h (559,234 mph) through our Milky Way Galaxy. It also...
Fast blue optical transients (FBOTs) share some characteristics with supernova explosions of massive stars and with explosions that generate gamma-ray...
Clusters of supernovas can cause the birth of scattered, eccentrically orbiting stars in outer halos of Milky Way-mass galaxies, according to new research...
An international team of astronomers has detected the brightest and most energetic known supernova: SN 2016aps.
An artist’s illustration of a supernova....
SN 2006gy, a superluminous supernova discovered in 2006, gained its exceptional brightness when a normal Type Ia explosion smashed into a dense shell of...
In 1054 CE, Chinese sky watchers witnessed the sudden appearance of a ‘new star’ in the heavens, which they recorded as six times brighter than Venus,...
Astronomers using ESO’s Very Large Telescope (VLT) have captured a stunning new image of the Milky Way’s densest region of stars, gas and dust, which...
X-ray images of Tycho’s supernova remnant (Tycho’s SNR) show a pattern of bright clumps and fainter holes. By comparing new data from NASA’s Chandra...
A new video released by NASA’s Chandra mission shows how Cassiopeia A has evolved over more than a dozen years in X-ray light.
Cassiopeia A, which is...
Astronomers have announced the discovery of the most massive star ever known to be destroyed by a supernova explosion. Dubbed SN 2016iet, the explosive...
A team of researchers from Germany, Austria and Australia has found traces of the radioactive isotope iron-60 — the tell-tale signature of a supernova...
Astronomers have used NASA’s Transiting Exoplanet Survey Satellite (TESS) to see what was happening around the supernova ASASSN-18tb in the first moments...
The NASA/ESA Hubble Space Telescope has produced a spectacularly detailed image of a spiral galaxy called NGC 4051.
This Hubble image shows the intermediate...
Astronomers using the 8-m Subaru Telescope have identified 1,824 new supernova candidates, including 58 Type Ia supernovae over 8 billion light-years away.
Supernovae...
Between 8 and 2 million years ago, cosmic-ray energy from one or more nearby supernovae reached Earth and pummeled the planet’s atmosphere, initiating...
